Definitions

  • This invention provides a flushing apparatus for a toilet or urinal, and a kit for retrofitting a flushing apparatus having manual activation means, for a toilet or urinal.
  • the Applicant is aware of a flushing apparatus for a urinal which is activated manually by a user. More recently, the Applicant has become aware of an electronic flushing apparatus which is activated after sensing a presence of a user proximate the urinal. However, when the electric supply (whether by battery or mains) to the electronic flushing apparatus is interrupted, activation thereof becomes impossible.
  • the flushing mechanism may be a conventional flushing valve which in use is connectable to a mains water supply such that it prevents water from passing through it in a normally closed orientation and allows water to pass through it to facilitate flushing when activated and thus opened.
  • the flushing apparatus 100 includes conventional manual activation means 4 having a push button 9 and a spindle 16 for activating the valve 2.
  • the spindle 16 is in turn pushed longitudinally inwards towards a telescopic pin 28 of the valve 2 until the spindle 16 pushes the pin 28, at a point proximate a lower end of the pin 28, radially with respect to the pin 28 causing the pin 28 to tilt within the valve 2.
  • the pin 28 is movable longitudinally within a plunger 17 of the valve 2 such that tilting of the pin 28 causes tilting of the plunger 17 within the valve 2.
  • a pressure seal 34 separates the pressure chamber 29 from the inlet 31.
  • the pressure differential between the pressure chamber 29 and the inlet 31 causes the piston 32 to move upwards into the pressure chamber 29.
  • the piston 32 seals the outlet 30 from the inlet 31 when the piston 32 is in a rest position on top of a sealing rim 13 of an upper aperture of the outlet 30, this upwards motion of the piston 32 in effect opens the valve 2 thereby allowing water from the inlet 31 to flow through the upper aperture of the outlet 30 into the outlet 30. The water then flows through a lower aperture of the outlet 30 and into the urine catchment portion of the urinal thereby flushing the urinal.
  • the plunger 17 returns to an untilted position thereby sealing the pressure chamber 29 causing the pressure chamber to be filled through the bypass aperture 27 which in turn causes the piston 32 to move downwardly until the valve 2 is closed.
  • the piston 32 moves downwards it causes the pin 28 to move downwards. If the button 9 is still held in, then the lower end of the pin 28 makes contact with a top of the spindle and further downwards motion of the piston 32 causes the pin to contract telescopically along its length.
  • buttons 9 are released before the lower end of the pin 28 rises above the spindle 16 thereby returning the pin 28 and the plunger 17 to an untilted position, then the release of the button 9 causes the pin 28 and plunger 17 to return to an untilted position immediately. This causes the pressure chamber 29 to start filling up through the bypass aperture 27 which in turn causes the piston 32 to move downwards until the valve 2 is closed.
  • the flushing apparatus 100 further includes an infrared sensor 41 for sensing a presence of a user proximate the urinal.
  • the flushing apparatus also includes sensed activation means in the form of a solenoid valve 45, activatable by the sensor 41 , for activating the flushing valve 2.
  • the solenoid valve 45 is housed within a first housing 52 which is adapted to fit onto a conventional cover 12 which houses the flushing valve 2, the conventional cover 12 also having being adapted to receive the first housing 52.
  • the first housing 52 and the conventional cover 12 are housed by a second housing in the form of an aesthetic cover 46 which is fitted onto the flushing apparatus 100 once the solenoid valve 45 and the first housing 52 have been fitted to the flushing valve 2.
  • the sensor 41 is also housed by the aesthetic cover 46.
  • the flushing apparatus 100 includes a power source, in the form of a battery 40, for the sensor 41 and the solenoid valve 45.
  • the solenoid valve 45 includes a pressure compartment 39 which separated, by means of a diaphragm 37 and a diaphragm seal 47, from the pressure chamber 29 of the flushing valve 2.
  • the pressure compartment 39 and pressure chamber 29 interact, when activated by the sensor, on a similar basis to the interaction between the pressure chamber 29 and the inlet 31, when activated by the manual activation means.
  • the solenoid valve includes a solenoid valve plunger 36 and a seal 48 attached to a lower end of the plunger 36, the seal 48 for sealing the pressure compartment 39 from a center flow path 54 of the diaphragm 37 when the seal 48 is in a rest position on top of an upper opening of the center flow path 54.
  • the sensor 41 emits an infrared beam, to detect the presence of a user, to a position which will be occupied by a user when using the urinal.
  • the sensor 41 activates an electric current from the battery 40 to the solenoid valve 45 thereby activating the solenoid valve 45 for a short period of time.
  • a flushing mechanism of a urinal is activatable by a user using manual means aswell as automatically by sensed activation means in response to the presence of the user being sensed.

Abstract

L'invention concerne un système de chasse d'eau (100) pour toilettes ou urinoirs, comprenant un mécanisme de chasse d'eau, sous forme d'une vanne de chasse (2), et des moyens d'actionnement manuels (4) destinés à actionner la vanne de chasse (2). Le système de chasse d'eau comprend également un détecteur (41) destiné à détecter, durant l'emploi, la présence d'un utilisateur à proximité des toilettes ou urinoirs, et des moyens d'actionnement détectés, sous la forme d'une vanne électromagnétique (45) mise en action par le détecteur (41), en vue d'actionner la vanne de chasse (2). Cette dernière comprend une chambre de pression (29) dépressurisable par les moyens d'actionnement manuels (4), et la vanne électromagnétique (45) en vue d'actionner la vanne de chasse (2). L'invention concerne également un kit pour raccordement d'un système de chasse d'eau, à moyens d'actionnement manuels, pour toilettes et urinoirs.
